Just wondering. Where do the electron microscope pictures come from?

I am neutral on this topic with no axe to grind, just interested in the daily flourishing of ideas.

I practised children's dentistry before and after the HIV episode in 1984 or thereabouts. Masks (and gloves ) were mandatory after 1984.

I seemed all my life to be prone to catching colds and sniffles, more so when I worked close to a patient and less so after masks were made mandatory. 40 years of clinical practice, half without masks, half with. Something is going on here, I will not speculate, I will follow Michael's rule here and stick to my knitting.
